/******************************************* IMPORTANT NOTE ABOUT SHARED MEMORY **************************************** \
This is a little note about the use of shared memory within the Area-Based Editor (ABE) programs. If you read
the Qt documentation (or anyone else's documentation) about the use of shared memory they will say "Dear [insert
name of omnipotent being of your choice here], whatever you do, always lock shared memory when you use it!".
The reason they say this is that access to shared memory is not atomic. That is, reading shared memory and then
writing to it is not a single operation. An example of why this might be important - two programs are running,
the first checks a value in shared memory, sees that it is a zero. The second program checks the same location
and sees that it is a zero. These two programs have different actions they must perform depending on the value
of that particular location in shared memory. Now the first program writes a one to that location which was
supposed to tell the second program to do something but the second program thinks it's a zero. The second program
doesn't do what it's supposed to do and it writes a two to that location. The two will tell the first program
to do something. Obviously this could be a problem. In real life, this almost never occurs. Also, if you write
your program properly you can make sure this doesn't happen. In ABE we almost never lock shared memory because
something much worse than two programs getting out of sync can occur. If we start a program and it locks shared
memory and then dies, all the other programs will be locked up. When you look through the ABE code you'll see
that we very rarely lock shared memory, and then only for very short periods of time. This is by design.
